A cutting insert adaptor for an insert pocket can include one or more pairs of opposing insert abutment surfaces and pocket abutment surfaces which converge at an acute angle. The one or more insert abutment surfaces are all rotated in the same direction, relative to their paired pocket abutment surface which in turn rotates a cutting insert abutting the cutting insert adaptor relative to an orientation the cutting insert would have if it only abutted the insert pocket instead of the cutting insert adaptor.

An insert adaptor is configured for providing secure clamping of an insert in an insert pocket. The insert adaptor is configured to be located between an insert and an insert pocket and includes at least one magnetic surface configured for applying a magnetic attraction force to the insert pocket or a shim.

A tool holder having a holder body, an opening of the holder body having opposing upper and lower jaws respectively defining upper and lower pocket surfaces of an insert receiving pocket, and a resilience slot extending away from the insert receiving pocket. A first plane intersects the upper and lower pocket surfaces, and an actuating member extends from the upper jaw along a first axis in a downward direction and traverses the resilience slot. The lower jaw includes an access bore, and a locking member occupies the access bore and engages a locking portion of the actuating member. The upper jaw has a top jaw surface facing in an upward direction, and the first axis intersects the top jaw surface. A cutting tool is configured with the tool holder and a cutting insert removably secured in the insert receiving pocket.

A turning tool for metal cutting includes a tool body with an insert seat, a clamping member and a clamping pin. The clamping pin connects the tool body and the clamping member to clamp a cutting insert in the insert seat. A shaft of the clamping pin is axially movably received in the tool body bore and moveable to a first axial position. The clamping pin, in the first axial position, engages the clamping member and forces the clamping member towards a tool body top surface, to clamp the cutting insert in the seat. In the first axial position, a first coolant fluid outlet opening in the head is located above a top surface of the clamping member. A locking mechanism, in the first axial position, releasably locks the shaft in the bore preventing axial sliding toward the tool body top surface.

The boundary flow path is constituted of a pair of boundary wall surfaces facing each other in a first cross section intersecting each of the first flow path, the boundary flow path, and the second flow path. An inclination of a tangent to at least one of the pair of boundary wall surfaces is continuously changed. In a second cross section perpendicular to a direction in which coolant flows, a lateral width of the first flow path is larger than a longitudinal width of the first flow path and a lateral width of the second flow path is larger than a longitudinal width of the second flow path when a longitudinal direction represents a direction in which the pair of boundary wall surfaces face each other and a lateral direction represents a direction perpendicular to the longitudinal direction.

A turning toolholder includes a shank, a club head, and a clamp and a clamp screw for clamping a cutting insert. The club head includes a clamp coolant supply hole in fluid communication, a flank coolant supply hole and an auxiliary rake coolant supply hole, all in fluid communication with the main coolant supply hole. Coolant is supplied through a rake coolant exit opening formed in the forward nose portion of the clamp to direct coolant to the top rake surface of the cutting insert, and coolant is supplied through a flank coolant exit opening located below the insert-receiving pocket to provide coolant to the side flank surfaces of the cutting insert. In addition, an auxiliary rake coolant supply housing formed on a top surface of the club head supplies additional coolant to the top rake surface of the cutting insert during high heat applications.

The invention relates to a distance compensating element for positioning reground cutting inserts in a cutting tool and to a cutting tool comprising such a distance compensating element. The cutting tool is provided with a cutting insert (16) and a tool holder (12), and the cutting insert (16) is releasably secured to the tool holder (12) in a cutting insert receiving area (14) by means of a clamping element (17) wherein the cutting insert receiving area (14) has a support surface (23) which substantially corresponds to the base shape of the cutting insert (16) and comprises at least one wall section (24) that extends vertically relative to the support surface (23) and is designed to align the cutting insert (16) in the cutting insert receiving area (14), and a blade (18, 19) of the cutting insert (16) protrudes freely. A distance compensating element (25) is arranged between the cutting insert (16) and the cutting insert receiving area (14) in order to position a reground cutting insert (16) in the cutting insert receiving area (14) in the correct position, said compensating element compensating for a removal of material when the cutting insert (16) is reground.

Tool for machining a workpiece having a cutting insert with at least one cutting edge. Moreover, the tool has a tool holder, which extends along a holder longitudinal axis and has at a workpiece-side end a cutting insert receptacle for receiving the cutting insert, the cutting insert receptacle having an upper clamping finger and a lower clamping jaw. Furthermore, the tool has a wedge-shaped clamping element, which is fastenable in the cutting insert receptacle for wedging the cutting insert in the tool holder. In addition, the tool comprises a fastening element for fastening the clamping element in the cutting insert receptacle and for wedging the cutting insert in the tool holder.

A cutting insert includes an insert peripheral surface that includes at least one planar major insert side abutment surface and an insert lower surface that includes an anti-slip recess recessed therein. The anti-slip recess includes at least one elongated and straight anti-slip groove. Each major insert side abutment surface is oriented parallel to a groove longitudinal axis of a respective anti-slip groove. An insert holder includes a holder pocket. The holder pocket includes a pocket peripheral surface which includes planar major pocket side abutment surface and a pocket base surface having an elongated and straight anti-slip rib. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the anti-slip rib is located in the anti-slip groove that is oriented parallel to the major insert side abutment surface that abuts the major pocket side abutment surface.

A toolholder includes a pocket assembly having a nest section and a clamp section. An inverted nest is mounted in the nest section and includes an insert-receiving pocket for accommodating a cutting insert mounted therein. A clamping wedge is mounted in the clamp section in such a way that the cutting insert engages the clamping wedge. The inverted nest includes one or more coolant grooves that cooperate with the cutting insert for directing super critical carbon dioxide to a cutting tool/workpiece interface.
